Implications This is the first study that couples ground-based Particulate Matter measurements with satellite retrievals to predict surface air pollution at Roda, Virginia. Roda is representative of the Appalachian communities that are commonly located in narrow valleys, or "hollows", where homes are placed directly along the roads in a region of active mountaintop mining operations. Our study suggests that proximity to heavy coal truck traffic subjects these communities to chronic exposure to coal dust and leads us to conclude that there is an urgent need for new regulations to address the primary sources of this particulate matter...

Implication Statement Infrared imager is an efficient tool for detecting gas leaks from process equipment and has been used in the Leak Detection and Repair (LDAR) programs for control of fugitive emissions. However, the information regarding which chemical compounds can be imaged and how sensitive a given infrared imager is for various compounds is limited. A theoretical method is presented in this paper that can answer these questions without conducting resource-intensive experiment. The results of this theoretical method has good agreement with experimental data...

This paper reports development and testing of novel cross-flow wet electrostatic precipitator (WESP), recently patented at Ohio University, which utilizes vertical columns of permeable material in the form of polypropylene ropes placed in a cross flow configuration within a flue gas stream. The cross flow design has large surface area, which provides scrubbing action; therefore it has the potential for removing multiple pollutants including particulates, gases, vapors and mists. In this new method, the ropes are kept wet by the liquid (water) introduced from the top of the cells running downward on the ropes by capillary action, making the permeable materials act as the ground electrode for capturing particles from the flue gas...

Implications Development of representative, engine dynamometer test-cycles, from in-use activity data, is crucial in understanding fuel efficiency and emissions for engine operating modes that are different from cycles mandated by the Code of Federal Regulations. Representative cycles were created for the prime movers of unconventional well development - OTR trucks, drilling and hydraulic fracturing engines. The representative cycles are implemented on scaled engines to reduce fuel consumption during research and development of new technologies in controlled laboratory environments...

It is well recognized that management of wastewater and sludge is a critical environmental issue in many countries. Wastewater treatment and the sludge production take place under different technical, economic and social contexts, thus requiring different approaches and involving different solutions. In most of cases, a regular and environmentally safe wastewater treatment and associated sludge management requires the development of realistic and enforceable regulations as well as treatment systems appropriate to local circumstances...

: Assessments of past environmental policies-termed accountability studies-contribute important information to the decision-making process used to review the efficacy of past policies, and subsequently aid in the development of effective new policies. These studies have used a variety of methods that have achieved varying levels of success at linking improvements in air quality and/or health to regulations. The Health Effects Institute defines the air pollution accountability framework as a chain of events that includes the regulation of interest, air quality, exposure/dose, and health outcomes, and suggests that accountability research should address impacts for each of these linkages...

Implication Statement This study demonstrates the ability to use airport visibility to estimate PM2.5 concentrations in Southwest Asian and Afghanistan. This supports the use of historical and ongoing visibility data to estimate PM2.5 exposure in this region of the world, where PM exposure information is otherwise scarce. This is of high utility to epidemiologists investigating the relationship between chronic exposure to PM2.5 and respiratory diseases among deployed military personnel stationed at various military bases throughout the region...

Nowadays our planet suffers from the accumulation of the plastic products which have a potential to cause a great harm to the environment in the form of air, water and land pollution. Plastic water bottles have become a great problem in the environment because of the mass numbers consumed throughout the world. Certain types of plastic bottles can be recycled but most of them are not. This paper describes an economical solvent free process that converts polyethyleneterephtalate (PET) bottles waste into carbon nanostructure materials via thermal dissociation in a closed system under autogenic pressure together with additives and/or catalyst which can act as cluster nuclei for carbon nanostructure materials as fullerenes and carbon nanotube...

A questionnaire survey was conducted to determine the current status of home medical care (HMC) waste collection by nurses for individual items and whether the collection rate differs with city size. The questionnaire was mailed to 1,022 nursing offices, of which 645 offices provided valid responses. Offices were classified into three groups according to the local population size. Responses indicated that used syringes and needles except for pen-type self-injection needles, was collected by >50% of HMC nurses...

Implications The performance of a low-cost PM sensor was evaluated in an urban residential area. Both PM2.5 and coarse PM (PM10-2.5) mass concentrations were estimated using a DC1700 PM sensor. The calculated PM mass concentrations from the number concentrations of DC 1700 were close to those measured with the Grimm 11-R when relative humidity was less than 60% for both PM2.5 and coarse PM. Particle size distribution was more important for the association of coarse PM between the DC 1700 and Grimm 11-R than it was for PM2...

Implication Statement Photolysis of HONO is a dominant source of morning OH radicals. Conventional traffic-induced HONO/NOx ratio of 0.8 % has possibly linked to under-estimation of the total HONO budget and consequently under-estimation of OH radical budget. Recently reported HONO/NOx ratio of c.a. 1.6 % was used to stimulate HONO emission, which resulted in increased HONO concentrations during morning peak hours and its impact to 14 % OH increment in the morning. However, the results were still lower than the measured concentrations...

Information regarding the magnitude and distribution of PM2.5 emissions is crucial in establishing effective PM regulations and assessing the associated risk to human health and the ecosystem. At present, emission data is obtained from measured or estimated emission factors of various source types. Collecting such information for every known source is costly and time consuming. For this reason, emission inventories are reported periodically and unknown or smaller sources are often omitted or aggregated at large spatial scale...

Periods of abnormally high concentrations of atmospheric pollutants, defined as air pollution episodes, can cause adverse health effects. Southern European countries experience high particulate matter (PM) levels originating from local and distant sources. In this study, we investigated the occurrence and nature of extreme PM10 pollution episodes in Greece. We examined PM10 concentration data from 18 monitoring stations located at five sites across the country: (1) an industrial area in northwestern Greece (Western Macedonia Lignite Area, WMLA), which includes sources such as lignite mining operations and lignite power plants that generate a high percentage of the energy in Greece; (2) the Greater Athens area, the most populated area of the country; (3) Thessaloniki; (4) Patra; and (5) Volos, three large cities in Greece...
